In 1559, a hurricane sent up to seven Spanish sailing vessels to the bottom of Pensacola Bay, hampering Don Tristan de Luna's attempt to colonize this section of the Florida Panhandle. Now, almost 500 years later, a second of those ships has been found, helping archaeologists learn about the settlement, which ended in 1561.

Some 650 pieces of artifacts — mostly pieces of pottery and wood — were on display Thursday for about 100 people who gathered at the north end of Pensacola Bay Bridge, about a half-mile from the shipwreck. No trace of it has ever been found on land.

"It's an amazing site," said University of West Florida nautical archaeologist Gregory D. Cook.
